A new study in ants demonstrates that living in groups leads to improved fitness. The researchers show that, in larger groups, ants take on specialized roles and colony stability increases.

Up until 40,000 years ago, at least two groups of hominins inhabited Eurasia — Neanderthals in the west and Denisovans in the east. Now, researchers have sequenced the genome of an ancient hominin individual from Siberia, and discovered that she had a Neanderthal mother and a Denisovan father.

Scientists have identified the sensor protein responsible for hearing and balance. The findings put an end to a 40-year quest for the protein that converts sound and head movement into electrical signals that travel to the brain.

Scientists have unraveled how changes in nutrition in the early development of honeybees can result in vastly different adult characteristics.

Researchers wanted to get a better idea why 18- to 24-year-olds, especially college students, have a higher tendency to waste food, and how their residence type — on or off campus — plays a role. Findings show that during the transitionary time of young adulthood, many of the food management behaviors that might prevent food waste haven't been learned yet or haven't been necessary.

Scientists reviewed the mechanisms responsible for vascular damage from air pollution.

The financial fallout from breast cancer can last years after diagnosis, particularly for those with lymphedema, a common side effect from treatment, causing cumulative and cascading economic consequences for survivors, their families, and society, a new study suggests.

A student spotted what looked like a 'smudge' last summer on deep sky images. Astronomers have now announced that it was very likely a new galaxy about 37 million lightyears away — a part of the Leo I galaxy group that is 'lowest surface brightness object ever detected via integrated light.'

In the fruit fly, a single pair of brain neurons command backward locomotion in both larvae and adults, researchers report. The methodology behind the discovery provides a way for scientists to link other direct connections between individual brain neurons and nervous system neurons.

Despite the 'illusion' of continuity, human perception pulses in and out four times per second, say researchers, a rate that is identical in human and monkey brains.
